BREECH-LOADING FlR-E-ARIVI.

SPECIFICATION forming part of Letters Patent No. 379,257, `dated March13, 1888.

Application filed April 17, 1884.

To all whom t may concern:

Be it known that we, REINHARD T. TORKEL- sON and IVER JOHNSON, both ofthe city and county of Worcester, and State of Massachusetts, haveinvented certain new and useful' Improvements in Fire-Arms, of which thefollowing is a specification.

Our invention relates to improvements in breech-loading fire-arms; andit consists in a novel arrangement of the locking-bolt and the hammer,whereby the bolt is Withdrawn by partially cocking the piece; also, inthe mech anism for actuating the extractor and means for rendering thismechanism inoperative.

In the accompanying drawings, Figure 1 is a side elevation, the stockand part of gunbody being removed. Fig. 2 isa longitudinal sectionthrough the parts shown in Fig. 1. Fig. 3 is a side elevation, partly insection, of a modified forni of our invention, and also shows the screwfor securing the barrel to the shell. Fig. 4 is a bottom view showingthe triggerguard. Fig. 5 shows the cartridge-extractor.

lThe hammer A is provided with a projection, a, which, on the firstmovement of the hammer when being cocked, engages one alm of abell-crank lever, a, provided with a spring, @that tends to depress thearm next the hammer and throws the other arm into a notch, b, in the lugb. The further movement of the hammer A raises one arm of the lever aagainst the spring a2 and withdraws the other arm from the notch b,thereby leaving the barrel B free to turn on its pivot b2, so as tobring its breech in position for receiving a cartridge. The lug b servesalso as a lsupport for parts of the cartridge-extractor mechanismhereinafter described, and is preferably employed for receiving thebolt-in this instance an arm of the lever a-for locking the barrel inposition f for firing. hen the usual sliding lockingbolt, b3, isdesired, it may be connected to the arm of the lever a' by a suitabledevice, such as a pin and slot, as shown in Fig. 3.

The trigger-guard d is inserted in aslot made in the under side of thebody D. To make this slot without filing or other hand-finish we use acircular cutter, which cuts it at one operation and makes its ends arcsof a circle. The

Serial No. 128,202. (No model.)

dotted 4lines in Figs. l and 2 indicate that part of the periphery ofthe circular cutter that enters the body in cutting the slot.

The guard d is shaped on a milling-machine, so that its surfaces whichcome in contact with the slot in the body D are also arcs of the samecircle, and consequently iit the slot accurately.

The cartridge-extractor consists of a plate, F, shaped on one edge tocorrespond with the lower half of the bore of the barrel and providedwith pinsff, which enter holes drilled lengthwise of the barrel andserve to guide the extractor. The plate F extends on each side of thebarrel to form projections f2 f3, by

means of which it may be pulled out. A projectiomf, on plate F entersnotch g in the end of the extractorslide G, thereby causing theextractor to move in both directions with its slide G. By means of agroove, g', in the upper bar of the slot coming in line with the pin gin its slot, the slide G is rendered capable of being tipped sulicientlyto allow the edge of the notch g to come below the projection f4L andrelease the plate F, so that the extractor may be withdrawn.

By making the extractor detachable dii'er ent styles of barrels may beused with one body, D. The slide G is actuated bya lever, g3, pivoted atg4 between the lugs b. One end of the lever g3 bears on the end of theslide G, and is caused to move the slide rearward by means of a springhook, gi', pivoted at g to the guard d. 'lhe hook g5 catches the otherend of thelever fas the barrel is tipped, and causes the lever to turnon its pivot until its end is withdrawn from the hook g5 by reason ofits movement in a circle having its center in the pivot b2. A spring,gs, located in the slot in the slide G, draws back the slide and theextractor as soon as the hook releases the lever g3. A tail, gl, to thehook g5 extends outwardly, so that by pressing on it with the thumb orfinger the hook may be thrown into an inoperative position, so as toallow the barrel to be tipped without expelling the cartridge.

In the arm shown the rear portion, b5, of the barrel B is made to tsnugly but detachably in the shell b, so that when in place the shelland barrel are practically one. A screw, bl, fitted in the fore lug, bs,at an angle, as shown in Fig. 3, enters a notch, b9, in the barrel andserves to draw the barrel and the shell together, and. efectuallyprevents any turning or displacement of the barrel.

We claim as our invention- 1. The barrel B, pivotcd at b2, and its lugb', in combination With the locking-bolt a, catch a, and hammer A, thelocking-bolt a being pivoted and the hammer A bearing against the catcha, also pivoted, to trip the lockingbolt a', substantially as and forthe purpose specified.

2. The barrel B, pivoted at b2, its lug` b, and extractor-slide G, incombination with lever g3, fulcrumecl at g, and springliook g5,fulcrumed in the fore part oi' the frame, the lever g3 acting upon slideG to force it rearward,

and the spring-hookg5 engaging therear end of leverg3, substantially asand for the purpose specified,

3. The barrel B, its lug b', and extractorslide G,in combination withleverg3,fulcrumed at g4, and spring-ho0k g5, provided with tailpiece 07,and fulcrumed in the fore part ofthe frame, the leverg3 acting uponslide G to force it rearward, spring-hook g5 engaging the rear end oflever g, and tailpiece g7 extending outside the frame, substantially asand for the purpose specified.
